An attempt was made to undermine the walls, but in vain; the commandant, Jurissitz, was far too vigilant to be reached by burrowing. Breach after breach was made in the walls, and as quickly repaired, or new walls built. Assault after assault was made and hurled back. Every effort was baffled by the skill, vigor, and alertness of the governor and the unyielding courage of his men, and still the days went by and still Guntz stood. Solyman, indignant and alarmed, tried the effect of promises, bribes, and threats. Jurissitz and his garrison should be enriched if they yielded; they should die under torture if they persisted. These efforts proved as useless as cannon-balls. The indomitable Jurissitz resisted promises and threats as energetically as he had resisted shot and balls. The days went on. For twenty-eight days that insignificant fortress and its handful of men defied the great Turkish army and held it back in that mountain-pass. In the end the sultan, with all his pride and all his force, was obliged to accept a feigned submission and leave Jurissitz and his men still in possession of the fortress they had held so long and so well. They had held it long enough to save Austria, as it proved. While the sultan's cannon were vainly bombarding its walls, Europe was gathering around Vienna in defence. From every side troops hurried to the salvation of Austria from the Turks. Italy, the Netherlands, Bohemia. Poland, Germany, sent their quotas, till an army of one hundred and thirty thousand men were gathered around Vienna, thirty thousand of them being cavalry. Solyman was appalled at the tidings brought him. It had become a question of arithmetic to his barbarian intellect. If Guntz, with less than a thousand men, could defy him for a month, what might not Vienna do with more than a hundred thousand? Winter was not far away. It was already September. He was separated from his flotilla of artillery. Was it safe to advance? He answered the question by suddenly striking camp and retreating with such haste that his marauding horsemen, who were out in large numbers, were left in ignorance of the movement, and were nearly all taken or cut to pieces. Thus ingloriously ended one of the most pretentious invasions of Europe. For three years Solyman had industriously prepared, gathering the resources of his wide dominion to the task and fulminating infinite disaster to the infidels. Yet eight hundred men in a petty mountain town had brought this great enterprise to naught and sent back the mighty army of the grand Turk in inglorious retreat. [Illustration: THE MOSQUE OF SOLYMAN, CONSTANTINOPLE.] The story of Guntz has few parallels in history; the courage and ability of its commander were of the highest type of military worthiness; yet its story is almost unknown and the name of Jurissitz is not classed among those of the world's heroes. Such is fame.
